What is a Codex Skill?

A Codex Skill is a specialized capability defined in a SKILL.md file that provides Claude with specific guidance, trigger keywords, and patterns for a particular task.

How do I trigger the Skill Builder?

You can trigger it by asking Claude to 'create a skill', 'add SKILL.md', or using Japanese phrases like 'スキル作成' or 'SKILL.md を追加して'.

Does this skill help with script-based tasks?

Yes, while it focuses on the SKILL.md instruction file, it also provides a framework for organizing and documenting supporting scripts in a scripts/ directory.

Where are the created skills stored?

Skills can be stored either locally within a project at .codex/skills/ or globally for your user account at ~/.codex/skills/.
